Professor Chronotis's TARDIS was disguised as the living quarters of Professor Chronotis at St. Cedd's College, Cambridge University. It was capable of holding another TARDIS within its force field and creating a bridge between the two to walk through.

It's controls were hidden behind wall panels and more simplistic than the controls of later TARDISes.

This TARDIS was a Type 12, Mark 1 TARDIS, a much earlier version than the Doctor's Type 40, which Chronotis had salvaged from the scrap heap before leaving Gallifrey. It could interfere in an individual's time stream, as Clare Keightley discovered when she reactivated the ship's controls, causing the previously deceased Chronotis to come back to life.
